Question

The length of diagonal of rhombus are 30cm and 16cm respectively . Find the length of each side of the rhombus . Also,find area of rhombus

Answer 1

the length of each side is

$\sqrt{(30 \div 2) {}^{2} + (16 \div 2) {}^{2} } cm \\ = \sqrt{225 + 64 \: } cm \\ = \sqrt{289} cm \\ = 17cm$

And the area is

$(1 \div 2) \times (30 \times 16) {cm}^{2} \\ = (1 \div 2) \times 480 \: cm {}^{2} \\ = 240 \: cm {}^{2}$
